Final answer:
Dialogue is a conversation between two or more characters in literature, plays, or movies that helps advance the plot and develop characters.
Step-by-step explanation:
Dialogue refers to communication between two or more characters in a written work like a movie, play, or novel. In narratives, aside from dialogue, there are monologues, where a character speaks alone to convey their thoughts, and soliloquies, similar to monologues but the character is alone on the stage.
These literary tools help progress the story and provide depth to the characters by revealing their thoughts and interactions. A dialogue is essential as it breathes life into characters and propels the story forward, creating a dynamic and engaging narrative experience, as can be seen in classic literature such as William Shakespeare's plays.
In literature, dialogue can make the difference between a vibrant scene and a dull narrative. Consider the interaction between characters in a novel or in plays like Shakespeare's Hamlet, where the dialogue directly reveals the character's intentions and feelings.
